New Shingle Roof & Rubber Porch Roof In Westport CT.

Here are some pictures of a job in Westport, CT that we just finished up. This roof was interesting because of a rubber porch roof that tied into the back of the main roof.

In the first image, you can see we started removing the old leaky roof with our roof to ground tarps set up. The second image shows where we installed the new rubber roof and our professional roofing crew tied the new Owens Corning True Definition Duration Shingles correctly to the home.

    Lisa L. of Danbury, CT

    Customer Testimonial

              This contractor was professional, thorough, knowledgeable, organized, and pleasant. He met with me to understand what work needed to be done and looked over the site. He provided an estimate and after the contract was signed and down payment made, he followed through on everything agreed to. He gave us a fair price and there were no surprises, we paid what was agreed upon. The work was completed efficiently, the workers arrived on time, when they said they would, and then followed up after the job was completed. I recommended them to my neighbor, who also used their services. I would definitely use them again!

    Joseph P. of East Haven, CT

    Customer Testimonial

              Millstream Construction was contracted to replace my roof. This company deserves nothing but praise. The owner Chris, contacted and kept me informed about my project, he was polite, professional and above all listen to my concerns and reassured me that the job would be completed as promised. He also followed up when the job was completed to see if I was satisfied. The crew arrived bright and early, got right to work. They were quick, neat, professional, polite and very very good at what they do. My roof came out awesome. Chris should be proud to have these men working for him. His job supervisor, Steve, did not just sit around. He worked just as hard. Steve and the other guys (don't know their names) worked hard and were done in several hours. They then cleaned my roof, washed my house, raked my lawn, swept my driveway. My property was immaculate when they left. I am a disabled police officer. This company I will highly recommend to anyone. Great company!

    Customer Testimonial

              Millstream Construction was very honest, up front, and timely. They kept me informed of any progress and of how things were going. They made sure I had a chance to go out and inspect the roof itself. Communication and timeliness were big positives for them. I would like to recognize the owner (Chistopher Gonsalves) and his project manager (Craig Kelso) for their exceptional service. I would definitely recommend Millstream Construction and I would use them again.

    Karen K. of Windsor, CT

    Customer Testimonial

              Millstream provided the highest quality roofing installation for our house. From our first meeting with Chris to completion, the entire Millstream team was professional, careful and respectful of us and our property. We highly recommend Millstream and would use them in the future whenever possible. A big thanks to Millstream for being quick and efficient and very sensitive to our needs. We can't thank them enough. They took care to shield our house when removing the old shingles. They also installed a new skylight skylight at the same time as the roof. They picked up all debris as it occurred and before they left each day. Their Owens Corning roofing products were in our estimation the best roofing system available. All work went according to plan and the work was completed in two consecutive days. The entire roof was water tight after the first day. The installers used safety gear when necessary and were very skilled. Damien, the on site manager ensured that the installers had plenty of water during the installation as it was warm on both days of the install. We felt very comfortable with the completed work. It was obvious that Chris understood the work needed to be done and was able to answer all of our questions prior to deciding to use Millstream for this project. You could tell Chris has hands on experience and was an expert in construction. We highly recommend Millstream Construction. Thanks

              We have used Millstream Construction twice and each time they have done a superb job. They were there when they said they were going to be there and finished on schedule. In passing we mentioned that we thought that there were birds getting into the attic in one of the houses and they went the extra mile and checked the attic for us - I was impressed with that. Very friendly and polite. Most definitely I would recommend this company.
